Lipid secretion from epidermal cells
The protective plant cuticle is formed by lipid secretion from epidermal cells to the plant surface. Cuticular waxes are uncommon secretory products made up of a wide range of very hydrophobic molecules such as saturated very long-chain alkanes, ketones, and alcohols. These chemicals are made in the endoplasmic reticulum (ER), but they must be transported to the plasma membrane by ATP-binding cassette transporters before they can be exported. To see if wax components are transported via the endomembrane system and packed in secretory vesicles produced from the Golgi.
